The latest to declare was North Norfolk Labour Party, which has chosen Cromer publisher Jen Emery as its candidate for the Cromer ward by-election on February 21.

Mrs Emery runs the independent publisher Salt Publishing in the town, alongside her husband Chris, and the company narrowly missed out on winning the Man Booker Prize for literature in 2012, with The Lighthouse, written by Alison Moore.

She lives in Cromer with her three children, who attend local schools. Before creating the publishing firm she spent 20 years working in the NHS.

Cromer town councillor and former mayor Tony Nash has been chosen by the town’s branch of the North Norfolk Conservative Association as its candidate.

Tony Nash.

The retired policeman lives locally with his wife Shay.

The Liberal Democrat candidate is Andreas Yiasimi, a well-known local personality whose family runs Constantia Cottage Restaurant at East Runton, where he is a popular front of house manager.

Mr Yiasimi is a photographer and music producer who lives in Cromer with his wife Angela and two children.

The seat is vacant after Mr Johnson shot dead his wife, Andrea, in a neighbour’s driveway at Compit Hills, Cromer, in December before turning the gun on himself. The couple were buried together on December 21.

Nominations must be received no later than noon on Friday January 25. They should be submitted to the returning officer at electoral services, NNDC, Holt Road, Cromer, NR27 9EN.
